Delock Ethernet LAN Converter to RS-232/RS-485/RS-422 and Modbus RTU/TCP Gateway with 1.5 kV Isolation

Legacy serial devices like RS-232, RS-485, and RS-422 equipment often lack network connectivity, making remote monitoring and integration into modern IP-based systems challenging. The Delock 63004 solves this by bridging serial interfaces to Ethernet, enabling seamless communication over LAN or the internet. It also functions as a Modbus gateway, converting between Modbus RTU and Modbus TCP, which is essential for industrial automation and building management systems. With 1.5 kV isolation between Ethernet and serial ports, it protects your equipment from ground loops and voltage spikes, ensuring reliable operation in harsh environments.

Who is it for

This converter is ideal for system integrators, industrial automation engineers, and IT professionals who need to connect legacy serial devices (such as PLCs, sensors, meters, or barcode scanners) to an Ethernet network. It is also suitable for building automation, energy management, and any application requiring Modbus protocol conversion.
